A lifetime annuity is a type of investment that guarantees an income stream for the rest of the retiree's life, states New Retirement. Financial advisers often recommend lifetime annuities over term annuities, which only guarantee payment for a specific number of years and have the potential to run out during a long retirement. The investor purchases an annuity with a lump sum payment, then receives his retirement income stream from this investment.
When choosing an annuity, it is important to consider factors that can affect a long retirement, such as inflation and the potential for a spouse to outlive the retiree. Some annuities include an annual cost-of-living adjustment to cover rising expenses during retirement, reports New Retirement. Married couples may prefer an annuity that provides lifelong benefits for a surviving spouse.Learn more about Investing
